Made it till wave 41. Start with Glock and buy the auto mod right away (don't forget to equip it), use short bursts and buy clip extender after the first mission, then laser scope if you feel like it. Buy secondary pouch and nothing else till AK-47. Buy the foregrip, scope and mobility upragde in that order. Don't try to hit technicals with grenades since it wastes lots of time, just aim for the weak spot. Always kill rocketeers first, technicals second and rest later. Later on just resupply A-10 strike and repair. Call in A-10 after 10 seconds because most technicals and rocket inf will be on the screen when it drops.
